Product Overview

A full-featured network management card, the CyberPower RMCARD305 remotely manages, monitors and controls select CyberPower UPS systems and ATS PDUs via a standard web browser, command line interface (CLI), SNMP or network management system (NMS). Especially suited to enterprise installations, the RMCARD305 provides scheduling for UPS shutdown, startup, and rebooting, along with event action settings, event logging, status recording, and automatic event notifications via email, SMS, SNMP traps, or Syslog.

An optional environmental sensor (ENVIROSENSOR) can be connected to the RMCARD305 to monitor the ambient temperature and humidity of a server room, IT closet, or other critical environments. Administrators define temperature parameters in Fahrenheit or Celsius; thresholds can be configured to prompt the RMCARD305 to send a predefined notifications. The RMCARD305 comes with a three-year warranty.
